Digital to Analog Converters

DAC8218SPAGR Description

The DAC8218SPAGR is a high-performance, 14-bit digital-to-analog converter (DAC) from Texas Instruments, designed for precision applications requiring multiple DAC channels. This IC features eight 14-bit DACs, making it ideal for systems that need multiple analog outputs. The DAC8218SPAGR operates with a wide analog supply voltage range of ±4.5V to ±18V and a digital supply voltage range of 2.7V to 5.5V, providing flexibility in power supply options. It utilizes an external reference, ensuring high accuracy and stability in its output.

The DAC8218SPAGR employs a string DAC architecture, which offers excellent linearity and low differential non-linearity (DNL) and integral non-linearity (INL) of ±1 LSB (max). This ensures highly accurate analog output signals. The device communicates via the SPI interface, allowing for efficient data transfer and control. With a typical settling time of 15µs, it can quickly respond to changes in digital input, making it suitable for real-time applications.
